I cannot reproduce the error with other files, so it seems like it’s something with the Glyphs file.
I’ve sent it to you. Could you try the update buttons and see if you get the same result with that file?
I don’t need it. But it has been generated automatically as most of my features are (see the file I send).
But now when I press “update features” in the bottom button all my features disappear. When I use the panel I get the script error you describe. Could you please let me know, what to do?
It may sound like a joke, but have you tried turning it off and on again? I’ve had the same thing happen to me randomly a handful of times without clear reason and no way of reproducing the error. After relaunching Glyphs, all worked as intended again.
The glyph is in the default glyph set of the “Oceanic” languages. From what I can tell from Wikipedia, that glyph should use a cedillacomb as component. Marshallese language - Wikipedia
But that article suggest that we need more alternates: Lcommaaccent.loclMAH, lcommaaccent.loclMAH, Ncommaaccent.loclMAH
ncommaaccent.loclMAH (all four are in confusion if they should use a cedilla or a comma. Most (European) languages need it ot be a comma, but Marshallese needs a cedilla).
I still have the issue that it removes all features when use the bottom “update features” button. But a temporary workaround is to use the features panel. But then it automatically generates this code:
